iTmux

itmux is a fast, modern SSH terminal built around tmux. Connect to your servers, attach to real tmux sessions that keep running when you disconnect, and pick up exactly where you left off — from iPhone, iPad, or Mac. Unlike a plain SSH client, itmux speaks tmux natively. It uses tmux control mode to show your sessions, windows, and panes as first-class UI, so switching context is a tap instead of a memorized shortcut. KEY FEATURES • Native tmux integration — attach to and create sessions, switch windows, and split or navigate panes without typing prefix keys. • Persistent sessions — your work keeps running on the server; reconnect any time and everything is still there. • Flexible SSH auth — connect with a password, an on-device SSH key, or your SSH agent. A key pair is generated and stored securely in the Keychain; only the public key ever leaves your device. • Fast, full-color terminal — a responsive renderer with true-color support and a touch-friendly key bar for Esc, Ctrl, arrows, and other keys phones don't have. • Tabs and windows — keep multiple sessions in tabs; on Mac, tear a tab off into its own window. • Remote file browser & editor — browse the server's filesystem and edit files in a built-in editor, without leaving the app. • Host-side notes — keep quick notes stored on the server alongside your work. • Built-in VNC viewer — open a remote desktop in a standalone window over your SSH tunnel. • Voice dictation — hold to speak a command straight into the terminal (iOS). • 14 languages — the whole interface localizes and switches instantly. BUILT FOR iPHONE, iPAD, AND MAC itmux is a universal app. The iPad layout gives you a proper sidebar and large terminal; the Mac app adds tear-off tabs and native window management. Your connections and SSH key live on-device, in the Keychain. PRIVACY FIRST No account required. Your hosts, passwords, and keys stay on your device and are used only to make your own connections — never sent to us. The contents of your sessions, files, and notes are never transmitted to our servers. See the privacy policy for details. Great for developers, sysadmins, and anyone who lives in the terminal and wants their tmux sessions in their pocket. Questions or feedback? Email hswillg@gmail.com — we read every message.
